IMPROVEMENT IN PAPER-RULING MACHINES.

Specification Aforming part of Letters Patent No. 134,833, dated January 14, 1873.

To all whom it may concern.-

Be it known that I, ALFRED HATHAWAY, of Freetown, of the county of Bristol, of the State of Massachusetts, have invented a new and useful Improvement in Paper-Ruling Machines, and for the purpose of raising out of action the pins thereof to form during the process of ruling paper one or more of what are termed headings, or unruled spaces; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing, of which- Figure l denotes a side elevation, Fig. 2 a top view, and Fig. 3 a horizontal section of such mechanism.

In the drawing, A denotes a circular disk pivoted to an arm, B, projecting from a rockshaft, such disk being arranged with the arm, as shown, over and directly over the bed or endless-apron roller C of a paper-ruling machine. The said disk should be capable of turning freely on the journal a, projecting from the arm, and be provided with a iiange, b, extending from one side of it at its circumference, all being as shown. There is arranged within the said ilange, and concentrically therewith, a flat ring, D, pierced with a series of screw-holes, c, arranged at equal distances apart around it. The ring D is placed at a short distance from and parallel to the disk A, and secured thereto at :intervals by studs or connections extending from one to the other. The said ring is to support one or more cams, E F, fastened to the ring by clamp-screws d going through slots e in such cams, and being screwed into holes in the ring, all being as shown. These cams E F, during a revolution of the disk, are intended to so act upon a lever or some device extending from or making part Vof or connected with the pen-carrier of the ruling-machine as to cause the pens to be raised and held out of action upon the paper while each cam may be passing the device against which it may so act. Each of the cams I usually make in two parts, f g, as shown, connected by a clampscrew, h, going through a slot, h', in one of such parts, and being screwed into the other. This enables each cam to be adjusted, or increased or diminished in width, as may be required, after having been placed in position approximately. Furthermore, there is applied to the iianged disk A, to cause it to adjust itself to the proper position for the reception of and action upon each sheet of paper, a mechanism which may be thus described: A bent arm, G, pivoted to the disk and arranged as shown, carries a friction-wheel, i, iixed to one side oi' it, the disk being notched or recessed, as seen at k, to receive the said wheel while it may be in the act of passing over the feed-apron roller. Over the arm, and connected with it by a link, l, is another arm, m, pivoted to the disk at xn. A part or arcal portion, o, of the ilange of the disk is movable or separate from the rest, and is hinged at one end to the disk A, there being jointed to such part o a pitman, q, extended to the arm m, as shown.

In advance of the arm G is a wedged lever or foot-piece, H, upon whose shorter arm the lower end of a latch, I, rests, the pivots of the lever and latch being represented at p and r, and the latch being provided with a spring, as shown at s.

When the friction-wheel t of the arm Gr, during each revolution of the disk, first strikes the endless apron on the roller, the rotation of the disk will be arrested and the disk will be in the correct position for a sheet of paper to be applied to it. The endless apron continuing in motion will carry the sheet of paper forward and force its advanced edge over the foot-piece H and against the spring-latch I in a manner to force the latter out of engage ment with the arm m. As soon as this takes place the wheel t' and arm Gwill be free to rise upward and the disk will revolve, the arcal part o being forced upward.

During the revolution of the disk the cams will edect the necessary elevations of the pens out of action upon the paper, and while the arcal part o may be passing across the feedapron roller it (the said arcal part) will be forced back to place in the periphery ofthe disk, and in so doing will cause the arm G and wheeli to be advanced so as to project the wheel beyond the disk. When thus projected beyond the disk the wheel will be latched in position by the latch I taking upon the end of the arm m, and thus when the wheel i may next be brought around against the endless apron such Wheel Will stop further rotation of the' disk A or set it for reception of the next sheet of paper.

In order to insnrethe disk moving with the paper at the proper time or times, more especially While the cam or cams may be in action, as explained, I affix to the ring D one or more serrated sectors, K K, suoli being formed and applied to the ring in manner as shown. The areal periphery of each sector has its radius of curvature equal to that of the periphery of the disk, the are being serrated or toothed.
